AI-generated Key Takeaways
-
The
BBox.distancemethod returns the minimum distance between two geometries. -
This method takes
right,maxError,proj, andsphericalas arguments. -
The output of this method is a Float value representing the distance.
-
Examples demonstrate using the
distancemethod in both JavaScript and Python.
| Usage | Returns |

)
|
Float |
| Argument | Type | Details |
|---|---|---|
|
this:
left
|
Geometry | The geometry used as the left operand of the operation. |
right
|
Geometry | The geometry used as the right operand of the operation. |
maxError
|
ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj
|
Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |
spherical
|
Boolean, default: false | If true, the calculation will be done on the unit sphere. If false, the calculation will be elliptical, taking earth flattening into account. Ignored if proj is specified. Default is false. |

// Define a BBox object. var bBox = ee . Geometry . BBox ( - 122.09 , 37.42 , - 122.08 , 37.43 ); // Define other inputs. var inputGeom = ee . Geometry . Point ( - 122.090 , 37.423 ); // Apply the distance method to the BBox object. var bBoxDistance = bBox . distance ({ 'right' : inputGeom , 'maxError' : 1 }); // Print the result to the console. print ( 'bBox.distance(...) =' , bBoxDistance ); // Display relevant geometries on the map.
